That is a good looking Detroit pie. The undercarriage looks more fried like Jets to me though. Buddys, when Ive had it, has a crisp bottom but not alot of crunch if that makes sense. Yours looks like it would have crunch, which I prefer in that style.
I can get brick cheese around here. It melts nice and tastes good, but I've never noticed much of a flavor difference between that and a mozzarella/muenster blend.
